Of course, the whole tournament structure must be changed, you just cannot play 3 rounds + final, because for entering the final you would need something like 3 GW and 14 to 15 VPs, and even then the finalist's seating at the final table would be determined almost all the time by a coin flip. So making tiered, multi-day tournament would be mandatory. But with 2,000 players, you cannot cut down the field of players with just one cut-off, because going down from 2,000 players to let's say 100 (=5%) would also easily require some 3 GW. So my proposal (totally fictional of course) would be to make such a large tournament a 3-day event. First day would be a tournament with 3 to 4 rounds (no final) in order to cut down the number of players to 400 (20%). Then on the second day play another 3 to 4 rounds to reduce the number to 80 (20%). The last day of such a tournament would be the final tournament with 3 rounds + finals, almost as normal ..
On second thought, a Swiss-system tournament style (as bad as it may be for multiplayer game like VtES) over two days, followed by regular tournament with, let's say 40-60 players would also be possible, I guess.
